MUSIC-LEAF TURNER.

Specification of Letters latent.

Patented Feb. 1,1916.

Application filed February 15, 1915. Serial No. 8,423.

To all whom it may concern:

Be it known that I, JOHN O. GREEN, a subject of the King of Great Britain, residing at Lost Lake, in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Music- Leaf Turners, of which the following is a specification.

The present invention relates to an improved music leaf turner and the main object thereof is to provide means for turning the sheet of music in a manner that will obviate bearing and the consequent defacement thereof; this being accomplished by the provision of a leaf engaging arm which has swivel connection with the main operating arm.

A further object is to provide a device of the above mentioned type which is especially adaptable for use by students and which includes means for oscillating the sheet of music and to return the same to its normal osition at the desire of theoperator in or- (161 that the same may be repeated.

Other objects will appear and be better understood in reading the annexed specification in connection with the accompanying drawings, in which Figure 1 is a front elevation; Fig. 2 isa fragmentary side elevation; Fig. 3 is a detail sectional view.

In the preferred embodiment of the in vention, an upright or standard 5 is pro vided to the lower end of which is secured a member 6. The member 6 comprises a socket ortion for engagement with the standar 5 and is formed with airs of ears or lugs 7 between which are a apted to be fitted the upper reduced ends of the legs 8. The engaging faces of the legs and lugs are corrugated or roughened so that when the thumb nut 9 is tightened on the bolt passing therethrough the legs will be held in their adjusted position. At its upper end, the is bifurcated to receive the lower reduced end of a support 10. A bolt passes through the bifurcated portion and the reduced end and has a thumb nut 11 threaded thereon to clamp the support in an adjusted position.

A rack 12 is carried by the support and has clips on its outer face to hold a note book or a piece of music thereon.

A rod 13 is carried by the support 10, projects laterally therefrom at a point below the rack 12, and at its outer end is provided a disk 14. The disk has a groove formed in its peripheral edge to receive a cord 15, the lower end of which passes through a guide 16 formed on the member 6 and is connected to a hinged member 17 carried by one of the legs 8. The cord passes partially around the groove of the disk 14 and has its end secured therein in any suitable manner. An arm 18 is carried by the disk 14 and has a bifurcated member 19 swiveled thereto for a purpose which will subsequently appear. A coil spring 20 is carried by the rod 13 and has one end secured to the disk 14 and the other end secured to the support 10, the purpose of which is to return the disk 10 to its normal position when pressure is released from the member 17.

In operation, the piece of music to be turned is placed on the rack 12 and held thereon by means of the clips engaging the cover of the same, the bifurcated member 19 is then positioned with the leaf to be turned within the bifurcated portion so that when the foot is pressed on the member 17 the disk 14 will be caused to rotate and the member 19 will carry the leaf to be turned therewith, the foot being held on the member 17 until the piece has been played through and then released to cause the members 14 and 19 to assume their operative position under the action of the spring 20.

The function performed by the member 11 will be readily obvious. During the movement of the disk 14, the arm 18 is moved in a plane corresponding with the vertical plane of the support. Therefore if a rigid member were used instead of the member 19, it would be found that the sheet of music would be torn at a point adjacent its connection with the back. Thus by the provision of the said swivel member, the sheet of music will be turned in accordance with the desire of the operator, yet in a manner that will obviate the tearing and consequent defacement thereof. As the arm 18 oscillates, the member 19 will move slightly outwardly and will turn during such movement so that when it reaches its outermost position, its position will be reversed. The greatest of stress is directed to the provision of this swivelly connected member as it is believed that the same greatly adds to the efficiency of my invention.

By havin the legs and the rack carrying support to old upon the standard 5, it will be readily seen that the bulk of the stand is considerably reduced thus providing a bundle that is easily carried from place to place.

While I have herein shown and described the preferred embodiment of my invention I wish to have it understood that I do not limit myself to the details of construction or arrangement of the parts herein shown and delineated, but minor changes may be made provided they fall within the scope of what is claimed.

1. Leaf turning mechanism including the combination with a support, a disk movably mounted on said support, a spring having connection with said disk and said support for normally retaining said disk in a normal position, means including a flexible element for moving said disk, an arm fixed to said disk, and a leaf engaging member having swivel connection with said arm for the purpose specified.

2. Lear" turning mechanism including the combination with a support, a disk movably mounted on said support, a spring having connection with said disk and'said support tor normally retaining said disk in a-normal position, an arm fixed to said disk, a leaf engaging member having swivel connection with said arm, means including a flexible member trained about said disk for moving the same, and means to actuate said flexible means-for the purpose specified.

3. Lear" turning mechanism including the combination with a vertical support, a disk movably mounted on said support, said disk being movable in a plane in parallelism with the vertical plane of said support, an arm fixed to said disk-and projecting radially beyond the periphery thereof, a leafengag-ing member having swivel connection with said Copies of this patent may be obtained for five cents each, by addressing the Commissioner Washington, D. 0.

arm, a flexible member trained about said disk for operating the same, and means in cluding a coil spring having connection with said disk and said support to return said disk to its normal position for the purpose specified.

4. Leaf turning mechanism including the combination with a vertical support, a disk revolubly mounted on said support, an arm fixed to said diskand projecting beyond the periphery thereof, a leaf engaging member having swivel connection with said arm, means including a flexible element trained about said disk for operating the same, means including a coil spring having a connection with said disk and said support to return said disk to its normal position, and an oscillatory member for actuating said flexible means, substantially as described.

5. Leaf turning mechanism including the combination with a vertical support, a disk revolubly mounted on said support, an arm fixed to-said disk and projecting beyond the periphery thereof, a leaf engaging member havingswivel connection with said arm, the upper end of said leaf engaging member be ing bifurcated to engage the sheet'of music, means: including a flexible element trained about said disk for operating the same, a coil spring having connection with said disk and saidsupport to return said disk to itsnormal position, and a pivoted member for actuatingsaid flexible means, substantially as described.
